2001-07-06 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/i386/sigaction.c (RESTORE2): Put asm explicitly into .text section. 2001-04-16 Jes Sorensen <jes@linuxcare.com> * sysdeps/unix/sysv/linux/ia64/bits/sigcontext.h (struct sigcontext): Add 16 longwords reserved for future use to match changes in the kernel. 2001-07-03 Jes Sorensen <jes@trained-monkey.org> * sysdeps/ia64/strncpy.S: Call strnlen() when determining the string length rather than strlen(). Solves the performance problem of doing strlen on a 5MB string when strncpy was called with a length argument of 5 bytes. 2001-07-02 Jakub Jelinek <jakub@redhat.com> * sysdeps/sparc/sparc32/dl-machine.h (elf_machine_rela): Handle R_SPARC_UA16 and R_SPARC_UA32. * sysdeps/sparc/sparc64/dl-machine.h (elf_machine_rela): Likewise. 2001-07-01 Stephen L Moshier <moshier@mediaone.net> * sysdeps/ieee754/ldbl-96/e_acoshl.c (__ieee754_acoshl): acosh(x) = ln(2x) if x > 2^30. * sysdeps/ieee754/ldbl-128/e_acoshl.c (__ieee754_acoshl): acosh(x) = ln(2x) if x > 2^54. * sysdeps/hppa/dl-machine.h (elf_machine_rela): Handle relocs
